Air conditioning system operation tips
• If the vehicle has been parked in dir
ect sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
• After sufficient cooling has been achieved, switch back from the
recirculated air to the fresh outside air
position.
• To help reduce moisture inside of the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the windows
and sunroof closed.
• Use the air conditioning system every month only for a few minutes
to ensure maximum system
performance.
• If you operate air conditioner excessively, the difference between
the temperature of the outside air and
that of the windshield could cause
the outer surface of the windshield
to fog up, causing loss of visibility. In
this case, set the mode selection knob
or button to the
position and fan
speed control to the lower speed.
System Maintenance
Cabin air filter
OIK047401LOIK047401L[A] : Outside air, [B] : Recirculated air
[C] : Cabin air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
The cabin air filter is installed behind
the glove box. It filters the dust or other
pollutants that enter the vehicle through
the heating and air conditioning system.
Have the cabin air filter replaced by an
authorized HYUNDAI dealer according to
the maintenance schedule. If the vehicle
is being driven in severe conditions such
as dusty or rough roads, more frequent
cabin air filter inspections and changes
are required.
If the air flow rate suddenly decreases,
the system should be checked at an
authorized HYUNDAI dealer.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning
is reduced. Overfilling also reduces the
performance of the air conditioning
system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.

Temperature conversion
If the battery has been discharged or
disconnect
ed, the temperature mode
display will reset to Centigrade.
To change the temperature unit from °C
to °F or °F to °C :
- Automatic climate control system
Press the AUTO button for 3 seconds while pressing the OFF button.
- Instrument cluster
Go to User Settings → Other → Temperature Unit.
The temperature unit on both the cluster
LCD display and the climate control
screen will change.
Air intake control
This is used to select the outside (fresh)
air position or recirculated air position.
To change the air intake control position,
push the control button.
Recirculated air position
With the recirculated air
position selected, air from the
passenger compartment will
be drawn through the heating
system and heated or cooled
according to the function
selected.
Outside (fresh) air position
With the outside (fresh) air
position selected, air enters
the vehicle from outside and
is heated or cooled according
to the function selected.
Information
Using the system primarily in Fresh mode
and Recirculation mode only when needed
is recommended for best results.
Prolonged operation of the heater in
Recirculation mode and without the A/C
ON can cause fogging of the windshield.
In addition, prolonged use of the A/C
ON in Recirculation mode may result in
excessively dry, dehumidified air in the
cabin.
WARNING
• Continued use of the climate control
system operation in Recirculation
mode for a prolonged period of
time may cause drowsiness to the
occupants in the cabin. This may lead
to loss of vehicle control which may
lead to an accident.
• Continued use of the climate control
system operation in Recirculation
mode with the A/C OFF may allow
humidity to increase inside the
cabin. This may cause condensation
to accumulate on the windshield and
obscure visibility.
• Do not sleep in your vehicle or
remain parked in your vehicle with
the windows up and either the
heater or the air conditioning ON for
prolonged periods of time. Doing so
may increase the levels of carbon
dioxide in the cabin which may lead
to serious injury or death.
